Haven't tried making memes, but this is a very powerful image editing app: https://github.com/T8RIN/ImageToolbox
F-Droid
F-Droid is an installable catalogue of FOSS (Free and Open Source Software) applications for the Android platform. The client makes it easy to browse, install, and keep track of updates on your device.

Thank you.
Isn't it mostly aimed at compression and file conversion?
I've used it when I learnt about jpegxl.
I really like the filter selection. It's the only open source app I know of that lets me blur images and that's pretty much all photo editing I do on my phone.
Fossify Gallery includes some basic editing
FFShare works nicely for reducing file sizes, but I wish it was more forgiving and did the conversion in the background. More than once I waited through the conversion and then accidentally closed it.
Termux also works well. Some tips:
- change the shell to something like Fish. Autocomplete helps a lot when typing on mobile
- set up some aliases for common commands
Image editor
- Fossify Gallery
- Snapseed (not FOSS, works without Google stuff with disabled Internet)
- Krita (UI only for tablets, complex, not very good for editing)
Image compression
- Signal/Signal-FOSS/Molly (just send to some person but save before sending and exit, saves as JPEG with removed EXIF and very compressed)
- ImagePipe
- ffshare (pretty weak compression)
- image toolbox (and other conversion)
Video cutting
- again, Signal (left-right cutting, compression, metadata)
- ffshare (compression)
- open video editor (strange UI, no more features than Signal)
Video editing
- open video editor:
